Inrush current?

7 years old 40 inches TV does not work as a digital terrestrial television.

Cable analogue TV tuner, TV, low frequency amplifier and CD player were plugged in the single table tap connecter with one switch, so the function was all on together and all off at the same time. The TV set was not put on and off not by the TV switch but by that of table tap connecter. The malfunction of digital tuner equipped in the TV set was caused by the switching habit for as long as 7 years, this is the opinion by my son.

If possible on his opinion, inrush current may be the reason, but many regulators inside? It's difficult to count it as a reason. According to the professional electric engineer, no connection with switching methods.

Now digital tuner equipped HDD recorder was newly obtained receiving all the digital terrestrial waves.
